pcntl“出于安全原因"不在 Ubuntu 上工作 [英] pcntl not working on Ubuntu 'for security reasons'
问题描述
我已经使用 这篇 文章.
它并不顺利,因为编译后,在运行 make test
时出现以下错误.每次尝试 fork 子进程时都会收到警告,内容为:
It didn't go smoothly at all because after compiling, when running make test
I got the following errors. I am getting a warning each time that I'm trying to fork a child process which says:
警告:出于安全原因,pcntl_fork() 已在第 8 行的/var/www/mydev/dev/mailServiceTest.php 中被禁用
Warning: pcntl_fork() has been disabled for security reasons in /var/www/mydev/dev/mailServiceTest.php on line 8
我在整个网络上搜索了解决方案,但不幸的是,我在其他任何地方都没有发现提及此问题.
I've searched all over the web for a solution, but unfortunately I didn't find any mentioning of this problem anywhere else.
Build complete.
Don't forget to run 'make test'.

You may have found a problem in PHP.
This report can be automatically sent to the PHP QA team at
http://qa.php.net/reports and http://news.php.net/php.qa.reports
This gives us a better understanding of PHP's behavior.
If you don't want to send the report immediately you can choose
option "s" to save it. You can then email it to qa-reports@lists.php.net later.
Do you want to send this report now? [Yns]: y

当输入以下命令时,似乎确实已经安装了PHP,尽管在我安装此扩展之前,PHP解释器根本无法识别该功能:
When typing the following command, it seems that PHP is indeed already installed, although the PHP interpreter didn't recognize the function before I installed this extension at all:
oleg@oleg-Lenovo-G580:/php/php-5.4.6/ext/pcntl$ php -m | grep pcntl
PHP Warning: Module 'pcntl' already loaded in Unknown on line 0
pcntl
如何配置此功能才能正常工作?
How can I configure this feature to work properly?
推荐答案
sudo gedit
sudo gedit
sudo gedit /etc/php5/cli/php.ini
或 \ 和
sudo gedit/etc/php5/apache2/php.ini
发现:
disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl
注释掉:
;disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl
